The effects of dark energy on the early universe with radiation and Bose-Einstein condensate

G. A. Monerat, F. G. Alvarenga, S. V. B. Gonçalves +4

This work analyzes the effects of quantization on a Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) model with positive curvature and material content composed of a Bose-Einstein cond…

Quantum Cosmology with many fluids and the choice of cosmological time

G. A. Monerat, C. G. M. Santos, F. G. Alvarenga +4

In this work we propose the quantization of a cosmological model describing the primordial universe filled with five barotropic fluids, namely: radiation, dust, vacuum, cosmic stri…

Quantum cosmology of a Hořava-Lifshitz model coupled to radiation

G. Oliveira-Neto, L. G. Martins, G. A. Monerat +1

In the present paper, we canonically quantize an homogeneous and isotropic Hořava-Lifshitz cosmological model, with constant positive spatial sections and coupled to radiation. We…

DeBroglie-Bohm interpretation of a Hořava-Lifshitz quantum cosmology model

G. Oliveira-Neto, L. G. Martins, G. A. Monerat +1

In the present letter, we consider the DeBroglie-Bohm interpretation of a Hořava-Lifshitz quantum cosmology model in the presence of a radiation perfect fluid. We compute the Bohm'…

The -expansion of the fermionic spinless Hubbard model off the half-filling regime

E. V. Corrêa Silva, M. T. Thomaz, O. Rojas

We found that when the spinless model is off the half-filling regime (), the Helmholtz free energy (HFE) can be written as two -expansions: one expansion comes from the…

On the particle-hole symmetry of the fermionic spinless Hubbard model in

M. T. Thomaz, E. V. Corrêa Silva, O. Rojas

We revisit the particle-hole symmetry of the one-dimensional () fermionic spinless Hubbard model, associating that symmetry to the invariance of the Helmholtz free energy of t…
